Question

我有一个带有选择输入的表单。我想在选择下拉列表时显示警告。视图：

<?php
echo $this->Form->create('Office');
echo $this->Form->input('under_office', array('type' => 'select', 'options' => $settings,'empty'   => false));
echo $this->Form->end('Save');
?>

控制器

public function add() {


    $settings = $this->Office->Officetype->find('list', array('fields'=> array('Officetype.id', 'Officetype.name')
    ));
      $this->set(compact('settings'));

        if ($this->request->is('post')) {
            $this->Office->create();
            $post_data = $this->request->data;
            if ($this->Office->save($post_data)) {
                $this->Session->setFlash(__('Office details saved successfully'));
                return $this->redirect(array('action' => 'add'));
            }
            $this->Session->setFlash(__('Unable to save Office details'));
        }
  }

这可能对您有所帮助，首先在您的选择标记上添加一些ID。

echo $this->Form->input('under_office', array('type' => 'select', 'id' => 'myselect', 'options' => $settings,'empty'  => false));

在执行上述代码之后，将代码放在<script> </script>标记之间或您的javascript存在的位置之下，

document.getElementById('myselect').onchange = function (){
    alert('hello guys');
}
